Abstract

A system includes a projector configured to project a plurality of non-coded elements onto an object, the projector having a first optical axis. The system includes a first camera having a first lens and a first sensor. The first lens defines a second optical axis. The system includes a second camera having a second lens and a second sensor. The second lens defines a third optical axis. The projector, the first camera, and the second camera are disposed on a substantially straight line in a first direction. The first optical axis is substantially parallel to the second optical axis, which is substantially parallel to the third optical axis. A center of the first sensor is displaced along the first direction away from the second optical axis, and a center of the second sensor is displaced along the first direction away from the third optical axis.
